This 50kVA, thirty six control channel unit, utilises six built-in P183 temperature controller/programmers to provide power and temperature control of up to thirty six ceramic pad heating elements rated at 30V, 45A, 1.35kW. This controlled power is used for preheating or post weld heat treatment of smaller diameter pipe welds, fabrication welds and other fabrications requiring controlled heating.

Application:

Where larger quantities of small diameter pipe welds require heat treating (e.g. boiler tubes), there are significant cost savings in utilising a unit that has been both specially designed for small diameter pipe or tube welds, and has a larger number of control channels.
